Title: Connecting structure of ceramic pipe
Inventor: TSUNODA HIDEO
IPC: B01D46/24
Filed: 1994-12-13
Abstract: PURPOSE: To restrain stress generated in ceramic pipe which is fragile and easy to break to the minimum to prevent breakage even when a mating member to be connected of a ceramic element undergoes large deformation by fitting a short metal pipe in the inside of a metal pipe fitted to an upper tubesheet through a seal material to slide freely. CONSTITUTION: Ceramics pipes 3, 4 are connected to a mating member through a packing placed on the upper or the lower part of the mating member. In connected parts 5, 6, 7, the packing is not stuck on at least one thereof, and a dead weight load of the upper member is only received in the compression direction to generate no restricting load. Even when high stress which is not anticipated such as earthquake occurs in a tubesheet, a space is left between both the members of the connected part to lower sealability, and this part acts as a safety device to cause dust leak only, and stress is not directly loaded on the ceramic pipes. The function of a sheet packing is to prevent a chip and to restrain dust and gas leakage to the minimum.

Title: Packaging method automatically case-packaging envelope or parcel envelope and automatic packaging machine executing said method
Inventor: BERUTO NORUTE
IPC: B65H33/02
Filed: 1987-12-08
Abstract: In the process of packaging letter envelopes and mailing wallets, the packaging batch is counted in the end region of the production machine, and the individual article of the packaging batch corresponding to the specific batch size is at least identified or optionally pushed a certain distance sideways out of the path of movement of the packaging batch in one direction or the other as a counting article. The packaging batch is deposited on a conveyor belt and conveyed away. A stack support keeps the stack approximately vertical on its end face. The stack support is advanced in front of the stack at the conveying speed of the conveyor belt. As soon as the counting article at the end of a stack has arrived at a transfer point which is at a relatively long distance from the production machine, a separating device is introduced into the stack, with the result that the following portion of the packaging batch is temporarily halted. During this time, the separated stack is pushed, at the same height, into an open container via a slide track. Subsequently, the stack support is guided back to the separation point, and the separating device is retracted from the end face of the following packaging batch, after which the stack support once again takes over the vertical guidance of the packaging batch, until the next counting article has arrived at the separation point. The automatic packaging machine for letter envelopes and mailing wallets has several devices, by means of which the individual steps of the process are executed partly alone and partly in combination with one another.

Title: Picture reader
Inventor: SUZUKI KATSUHIRO
IPC: H04N1/04
Filed: 1987-12-09
Abstract: PURPOSE:To attain accurate picture reading by providing a reference line in parallel with the reading direction along the original face, providing a reference line detection means receiving an electric signal to detect the reference line and outputting the correcting signal to correct the read range of the original. CONSTITUTION:The signal pattern at points A, B differs in a reader whose optical system is tilted, that is, in a reader where the direction to be scanned is not spatially in parallel with the actual scanning direction. Since an interval alphabetween an original 2 and a reference line 9 to read the original is identical anywhere on the scanning line, the reference line 9 and the original face are read by a reference line detector 7 for each line in the case of reading the original 2. Then it is recognized that a point with a constant distance alpha from the reference line 9 is the edge of the original 2 at all times in the case of deciding the effective width of the read original 2 to apply the correction decoding the effective width of the original 2 to be read from that point. Thus, a picture signal without any tilt is obtained in the reading in the reader whose optical system is tilted.

Filed: 1987-12-07
Abstract: PURPOSE:To augment the circuit bonding strength by a method wherein, after printing electric circuits with a conductive material on the surface of a resin sheet, the circuit parts are electroplated. CONSTITUTION:Electric circuits are printed with a conductive material on the surface of a resin sheet and then the circuit parts are electroplated. At this time, it is recommended that the resin sheet is a laminated sheet made of specific number of resin-impregnated substrates which are lamination-formed into one body. Besides, the practical thickness of the resin layers of 0.2-2.0mm is preferable. Such a printed wiring sheet can eliminate any etching process to augment the bonding strength between the electric circuits and the resin sheet, thereby enabling the humidity resistance to be maintained further because such a material as Pd is not employed.
